Question

The diagram below, not drawn to scale, represents a segment of the graph of the function
f(x)=x^3+mx^2+nx+p
where m,n and p are constants.
Find
(i) the value of p
(ii) the values of m and n
(iii) the x-coordinate of the point Q. The diagram below, not drawn to scale, represents a segment of the graph of the function
